To all 'whom it may concern:

Be it known that l, FRANK lneonnsnr, a citizen of the United States.vresiding at St. Louis and Starte ot Missouri, have invented a. certainnew and useful Improvement in Dump-Cars, of .which the follmving is afull, clear, and exact description, reference being had to theaccompanying drawings.

The object.. of this invention is to provide simple and etlicient meanstorreceiving tlc impact' ot dropping doors in dump cars, 1.. ef ventingany distortion thereot.

The invention isl welladapt'ed for cars of the Ingoldsby typefvrhereinthere is a central longitudinal member, to the opposite edges ot' whichare hinged doors norn'iaily horizontal when closed, but ,rhich downwardat their outer edges to discharge the load. In such cars, Ihavecustomarily provided a pair oi bumpers to receive the door as itdrops, these bumpers being conveniently located a suitable distanceinward from the end of the door. These bumpers have engaged springscarried on the under side of the door by the next to the end floor beamsthereof. Vit-h such arrangement l have found there is a tendency ot' theeX- treme corner of the door to bend downward from successive impacts.

The present invention is designed primarily to preventthe downwardbending at the corner of the door. Itv provides a aprire extendingcrosswise olf the car carried b the central structure and adapted toreceive the doors on its opposite sides. This spring is shown as locatedin position to engage the end licor beam and thereby support the cornersof the doors-the spring being used in addition to the usual bumpers anddoor springs. In some classes or" cars, however, my new spring carriedby the car structure may be used in place of the bumpers and tloorsprings, and thus receive and support the whole. impact of the droppingdoor. My spring .so has the advantage. ot acting as a strut-tie acrossthe bottom oit the central structure di the ear. These features, andother features involved in the securing of the ring', will behereinafter' more fully exixglained, and the essential characteristicssetoutin the claims.

In the drawings Figure 1 is a bottom plan of a `portion or a carel'nbodying my invention* Fig. 2 is a cross section of such car. Fig. 3is a detail in the same plane with Fig.

prised of the vertical plates 12 a surmounting `ridge 13, thecrossbracing plates 14 be tween the outer sides of the vertical platesand the under side of the projecting ridge7 and the through angle bars15,.extending lalong the lower portions of the plates 12 at their outersides, being riveted to them.

16 indicates dumping doors which are hinged their inner ends `by meansof ioor beams 17 which are'connected by hinge pintles to the straps 1Ssecured. to the cross plates 11i. The outer ends of the doors 16 abutthe lower edges of the car side, where they are supported by suitablehooks 19 on the sides or the car engaging beneath the projecting ends ofthe floor beams. The floor beams extend through the Z-bar 27, the pur)ose of which is to stiilen the outer edge of the door.

2O indicates rock shafts supported by some of the straps 18, and 21indicates arms on these rock shafts adapted to engage the under sides ofthe doors and raise them when the shafts are properlyrocled.

23 represents a suitable -beani extending rosswise of the car beneaththe angles 15 and rivet-ed thereto. rl`his I-beam is cutoii" diagonallyas shown, and the end of its lower` iiaiige and the lower portion of itsweb forms a bumper adapted to engage a leaf spring 25 carried oul theunder side of the door. These leaf springs are shown as carried by thedoor beams 17 which are next to the end iioor beams of the doors, asseen in F ig. l, and the bumpers are correspondingly located.

The construction so tar specifically de-v scribed is employed in cars lhave hereto tore devised, and which are the subject of various priorapplications. ln those applications, the construction of the centermeniber, the doors, the door raising mechanism and the bumper andsprings are set ont. and claimed. The presentapplicat-ion relatesparticularly to my new bumping spring car- CIK ried by the centermember, which will non7 be described.'

My nepY bninpin pring consists of a sub stantiaily rectanguiar bar 3Gextending crosswise of the car beneath the angles l and curvingdownward. near its ends, as shown at 3l, rIhis spring is shown as solofd that its curved portion receives the Ver 1.' cal web oi 'theendmost iioor beam 17 The left hand half of Fig, 2 door beam l? engagingthe Y The spring is sr iported first by shackles which ezfrtend aroundit7 and project upwardly through ope gs in thehorizontal iia We ot theangle loi nnte Se sereni'- ing onto ich projecting ends oil" theshackle. This siivports the spring without in any manner weakening it atIits point ot iler-nro To prevent the :ing shittingvinng tudinally,however, I pass a bolt through it, which extends into the horizontalflange of asmail angular piece 36 rivet i' side of the plate l2. The c"the spring bar for this bols located far enough haelt -from the point offiemire so that it does not weaken the spring. @he of the same rivets3'? which secures the angle to the plate 2O ay also secure the piece 36.This same rit-'et may likewise pass through the Hangs i0 of the crossplate 14..

It will be seen that the spring bar is, by the construction described,held rigidly in place, While its ends are in position to receive thedoors and prevent any distortion of the same. The intermediate portionof the s `ng bar acte also as a strut-tie across the con-s: member,binding together the two plates lf2 Witii`-tiicir angles 15 andassisting in bracing the center member.

I-Iaving thus described my invention, I claim:
